Product details

2.5 V fixed output, 3 ppm/°C drift — precision reference for industrial ADCs

It is designed for precision data-acquisition chains where the reference voltage directly sets the ADC or DAC full-scale range. Low-frequency noise is specified at 3 µVp-p over the 0.1 Hz to 10 Hz band — this is the noise floor that limits the effective resolution of a 16-bit or 24-bit sigma-delta converter. The 10 mA output current capability lets it bias multiple converter reference inputs or a small resistive divider network without an external buffer.

Input range and supply current — sizing the rail

The 1.2 mA quiescent supply current is the load-independent overhead; at 10 mA output the total current draw is 11.2 mA.

Frequently asked questions

What is the tolerance and temperature drift of the REF5025IDRG4?

Initial tolerance is ±0.05%.

Is the REF5025IDRG4 compatible with the REF5025IDR?

Yes, the REF5025IDRG4 and REF5025IDR are functionally identical. The only difference is the packaging format: the IDRG4 suffix indicates tape-and-reel, while the IDR suffix typically ships in tubes or another carrier. Both share the same die, output voltage, tolerance, and temperature range.
